OmniAuth OAuth2
This gem contains a generic OAuth2 strategy for OmniAuth. It is meant to serve
as a building block strategy for other strategies and not to be used
independently (since it has no inherent way to gather uid and user info).
Creating an OAuth2 Strategy
To create an OmniAuth OAuth2 strategy using this gem, you can simply subclass
it and add a few extra methods like so:
require 'omniauth-oauth2'
module OmniAuth
module Strategies
class SomeSite < OmniAuth::Strategies::OAuth2
# Give your strategy a name.
option :name, "some_site"
# This is where you pass the options you would pass when
# initializing your consumer from the OAuth gem.
option :client_options, {:site => "https://api.somesite.com"}
# These are called after authentication has succeeded. If
# possible, you should try to set the UID without making
# additional calls (if the user id is returned with the token
# or as a URI parameter). This may not be possible with all
# providers.
uid{ raw_info['id'] }
info do
{
:name => raw_info['name'],
:email => raw_info['email']
}
end
extra do
{
'raw_info' => raw_info
}
end
def raw_info
@raw_info, = access_token.get('/me').parsed
end
end
end
end
That's pretty much it!
